Establishing full enteral feeds is a vital aspect of their clinical care. Evidence predominantly from high income countries shows that early and rapid advancement of feeds is safe and reduces length of hospital stay and adverse health outcomes. However, there are limited data on feeding practices and factors that influence the attainment of full enteral feeds among these vulnerable infants in sub-Saharan Africa. Aim To identify factors that influence the time to full enteral feeds, defined as tolerance of 120ml/ kg/day, in hospitalised preterm and VLBW infants in neonatal units in two sub-Saharan African countries. Methods Demographic and clinical variables were collected for newborns admitted to 7 neonatal units in Nigeria and Kenya over 6-months. Multiple linear regression analysis was conducted to identify factors independently associated with time to full enteral feeds. Results Of the 2280 newborn infants admitted, 484 were preterm and VLBW. Overall, 222/484 (45.8%) infants died with over half of the deaths (136/222; 61.7%) occurring before the first feed. The median (inter-quartile range) time to first feed was 46 (27, 72) hours of life and time to full enteral feeds (tFEF) was 8 (4.5,12) days with marked variation between neonatal units. Independent predictors of tFEF were time to first feed (unstandardised coefficient B 1.69; 95% CI 1.11 to 2.26; p value <0.001), gestational age (1.77; 0.72 to 2.81; <0.001), the occurrence of respiratory distress (-1.89; -3.50 to -0.79; <0.002) and necrotising enterocolitis (4.31; 1.00 to 7.62; <0.011). Conclusion The use of standardised feeding guidelines may decrease variations in clinical practice, shorten tFEF and thereby improve preterm and VLBW outcomes

Roll out of a successful antimicrobial stewardship programme in Lagos University Teaching Hospital Nigeria using the Global-Point Prevalence Survey

Background: Antimicrobial resistance (AMR) has become a public health emergency with increasing rates and spread globally. Antimicrobial stewardship (AMS) has been advocated to reduce the burden of antimicrobial resistance, promote rational and appropriate use of antibiotics and improve clinical outcomes. Education and training are one of the AMS interventions to improve antimicrobial use. We present the roll out of a successful AMS programme with education and training using the Global-PPS as data collection tool to measure AMS interventions and impact.Methodology: This was a cross sectional study on the implementation of an AMS programme at the Lagos University Teaching Hospital. Global PPS was conducted in 2015 to collect baseline data which was used to identify targets for quality improvement in AMS and was repeated in 2017 and 2018 to measure impact of AMS interventions. AMS interventions included education, feedback of Global-PPS result and writing of the hospitalwide antibiotic policy based on the baseline data.Results: Out of the 746 inpatients surveyed, 476 (68.3%) had received at least one antimicrobial on the days of Global-PPS. The antimicrobial prescribing rates reduced significantly over the three time periods. In 2015, 82.5% were placed on antimicrobials, 65.5% in 2017 and 51.1% in 2018 (p<0.00001). The documentation of indication for treatment significantly improved from 53.4% in 2015 to 97.2% in 2018 (p<0.0001). Stop review date also significantly improved from 28.7% to 70.2% in 2018 (p<0.00001). Surgical prophylaxis for more than 24 hours reduced significantly from 93.3% in 2015 to 65.7% in 2018 (p=0.002) even though the prevalence was still high. The three most commonly administered antimicrobial groups were third generation cephalosporins, imidazole derivatives and quinolones. The most commonly prescribed antibiotics for surgical prophylaxis were ceftriaxone and metronidazole in 2015 and ceftriaxone in 2017.Conclusion: The use of education and training as AMS intervention in a limited resource setting clearly made impact on antimicrobial prescribing patterns in the hospital. Global-PPS is useful to set quality improvement targets and for monitoring, evaluation and surveillance of an AMS programme. Keywords: Antibiotic, Stewardship, Resistance, Education, Global-PP

Pediatric Bacterial Meningitis Surveillance in Nigeria From 2010 to 2016, Prior to and During the Phased Introduction of the 10-Valent Pneumococcal Conjugate Vaccine

Background: Historically, Nigeria has experienced large bacterial meningitis outbreaks with high mortality in children. Streptococcus pneumoniae (pneumococcus), Neisseria meningitidis (meningococcus), and Haemophilus influenzae are major causes of this invasive disease. In collaboration with the World Health Organization, we conducted longitudinal surveillance in sentinel hospitals within Nigeria to establish the burden of pediatric bacterial meningitis (PBM). Methods: From 2010 to 2016, cerebrospinal fluid was collected from children <5 years of age, admitted to 5 sentinel hospitals in 5 Nigerian states. Microbiological and latex agglutination techniques were performed to detect the presence of pneumococcus, meningococcus, and H. influenzae. Species-specific polymerase chain reaction and serotyping/grouping were conducted to determine specific causative agents of PBM. Results: A total of 5134 children with suspected meningitis were enrolled at the participating hospitals; of these 153 (2.9%) were confirmed PBM cases. The mortality rate for those infected was 15.0% (23/153). The dominant pathogen was pneumococcus (46.4%: 71/153) followed by meningococcus (34.6%: 53/153) and H. influenzae (19.0%: 29/153). Nearly half the pneumococcal meningitis cases successfully serotyped (46.4%: 13/28) were caused by serotypes that are included in the 10-valent pneumococcal conjugate vaccine. The most prevalent meningococcal and H. influenzae strains were serogroup W and serotype b, respectively. Conclusions: Vaccine-type bacterial meningitis continues to be common among children <5 years in Nigeria. Challenges with vaccine introduction and coverage may explain some of these finding. Continued surveillance is needed to determine the distribution of serotypes/groups of meningeal pathogens across Nigeria and help inform and sustain vaccination policies in the countr

Strengthening retinopathy of prematurity screening and treatment services in Nigeria: a case study of activities, challenges and outcomes 2017-2020.

OBJECTIVES: Retinopathy of prematurity (ROP) will become a major cause of blindness in Nigerian children unless screening and treatment services expand. This article aims to describe the collaborative activities undertaken to improve services for ROP between 2017 and 2020 as well as the outcome of these activities in Nigeria. DESIGN: Descriptive case study. SETTING: Neonatal intensive care units in Nigeria. PARTICIPANTS: Staff providing services for ROP, and 723 preterm infants screened for ROP who fulfilled screening criteria (gestational age <34 weeks or birth weight ≤2000 g, or sickness criteria). METHODS AND ANALYSIS: A WhatsApp group was initiated for Nigerian ophthalmologists and neonatologists in 2018. Members participated in a range of capacity-building, national and international collaborative activities between 2017 and 2018. A national protocol for ROP was developed for Nigeria and adopted in 2018; 1 year screening outcome data were collected and analysed. In 2019, an esurvey was used to collect service data from WhatsApp group members for 2017-2018 and to assess challenges in service provision. RESULTS: In 2017 only six of the 84 public neonatal units in Nigeria provided ROP services; this number had increased to 20 by 2018. Of the 723 babies screened in 10 units over a year, 127 (17.6%) developed any ROP; and 29 (22.8%) developed type 1 ROP. Only 13 (44.8%) babies were treated, most by intravitreal bevacizumab. The screening criteria were revised in 2020. Challenges included lack of equipment to regulate oxygen and to document and treat ROP, and lack of data systems. CONCLUSION: ROP screening coverage and quality improved after national and international collaborative efforts. To scale up and improve services, equipment for neonatal care and ROP treatment is urgently needed, as well as systems to monitor data. Ongoing advocacy is also essential

Determination of lead levels in maternal and umbilical cord blood at birth at the Lagos University Teaching Hospital, Lagos.

BACKGROUND:Lead toxicity is a cause of intellectual disability in children and majority of affected children live in developing countries. Its adverse effect on pregnancy outcome has also been documented. OBJECTIVES:To assess the relationship between maternal blood lead levels and umbilical cord blood lead levels in their corresponding newborn infants; to determine factors associated with high blood lead levels and the pregnancy outcome in participants. MATERIALS AND METHODS:This was a cross-sectional descriptive study carried out at a tertiary Teaching Hospital, Lagos, Nigeria. Four hundred and forty pregnant women and their respective newborns delivered at the study centre. Blood samples were obtained from the mothers and umbilical cord of the newborns at delivery and analysed by atomic absorption spectrophotometry. Socio-demographic and obstetric data was obtained by questionnaires administered to the mothers. The anthropometric measurements of the babies were taken at birth and clinical data recorded. Main outcome measures were blood lead levels in mother and baby pair, socio-demographic factors, birth weight, gestational age, length, occipito-frontal circumference. RESULTS:The median maternal and umbilical blood lead level was 64.3μg/dl and 39.2μg/dl respectively. The levels were above 5μg/dl in 75.6% and 66.8% of mothers and umbilical cord respectively. There was a strong positive correlation between the maternal and umbilical cord blood lead levels (rs = 0.80). Use of calcium supplements during pregnancy was significantly associated with a lower maternal blood lead level (p = 0.010) while recent painting and renovation of residential accommodation were associated with a higher umbilical cord blood lead level (p = 0.025). There were no statistically significant associations between the maternal and umbilical cord blood lead levels and the gestational age and anthropometry of the newborns at birth. CONCLUSIONS:The blood lead levels in newborns of women residing in Lagos, Nigeria are high and administration of antenatal calcium is associated with lower blood lead levels

Prevalence Of Iron Deficiency In Children 6-24 Months In Lagos

Background: iron deficiency is the commonest cause of nutritional anaemia in children worldwide particularly in developing countries. Infants and toddlers are prone to developing iron deficiency anaemia (IDA). This study was carried out to determine the prevalence of IDA and some factors associated with it in this group of children. Study Design: In a study, haemoglobin concentration and mean corpuscular volume (MCV) estimations done in 282 apparently well children aged 6-24 months. Estimations of serum iron (SI), total iron binding capacity (TIBC), serum ferritin (SF) and transferrin saturation (TS) were also determined in children with anaemia (Hb concentratio

Marked variability in institutional deliveries and neonatal outcomes during the COVID-19 lockdown in Nigeria

Background The coronavirus disease 2019 (COVID-19) pandemic and the interventions to mitigate its spread impacted access to healthcare, including hospital births and newborn care. This study evaluated the impact of COVID-19 lockdown measures on newborn service utilization in Nigeria. Methods The records of women who delivered in hospitals and babies admitted to neonatal wards were retrospectively reviewed before (March 2019–February 2020) and during (March 2020–February 2021) the COVID-19 pandemic lockdown in selected facilities in Nigeria. Results There was a nationwide reduction in institutional deliveries during the COVID-19 lockdown period in Nigeria, with 14 444 before and 11 723 during the lockdown—a decrease of 18.8%. The number of preterm admissions decreased during the lockdown period (30.6% during lockdown vs 32.6% pre-lockdown), but the percentage of outborn preterm admissions remained unchanged. Newborn admissions varied between zones with no consistent pattern. Although neonatal jaundice and prematurity remained the most common reasons for admission, severe perinatal asphyxia increased by nearly 50%. Neonatal mortality was significantly higher during the COVID-19 lockdown compared with pre-lockdown (110.6/1000 [11.1%] vs 91.4/1000 [9.1%], respectively; p=0.01). The odds of a newborn dying were about four times higher if delivered outside the facility during the lockdown (p<0.001). Conclusions The COVID-19 lockdown had markedly deleterious effects on healthcare seeking for deliveries and neonatal care that varied between zones with no consistent pattern
